HORSEPOWER SPECIFICATIONS

RPM GPM 500P SI 1000 PSI 2000 PSI 3200 PSI
725 0.9 0.31 0.62 1.2 2.0
900 1.1 0.38 0.76 1.5 2.4

Horsepower Requirements

The ratings shown are the power requirements for the pump. Gas engine power outputs must be approximately twice the pump power requirements shown above.

We recommend a 1.15 service factor be specified when selecting an electric motor as the power source. To compute specific pump horsepower requirements use the following formulas:
Electric HP = (GPM X PSI)/1450
Gas HP = (GPM X PSI)/1100


*Engine power varies based on horizontal or vertical orientation, as well as by makes and models from each manufacturer.
